These in-ear buds use a patented Twist-Lock Technology instead of pronounced bud tips to stay secure throughout all physical activity. The in-ear style means that you can expect a crisper, clearer sound that eliminates some ambient noise, but not enough to disconnect you completely. The sweatproof, water-resistant buds remain snug as they mold to your ears, and a clip for the cord prevents additional flailing. The cloth-covered cord ensures that it won’t tangle and comes with a case for post-workout storage. Yurbuds also includes an extra pair of changeable buds in case you wear out these comfortable earphones (and you’ll want to).
